BOX.

SPECIFICATION forming part of Letters Patent No. 695,557, dated March 18, 1902.

- Application filed Oetoberll, 1991. Serial No. 78,078. on model.)

a resident of St. Louis, inthe State of Missouri, have invented certain new and useful Improvements in Boxes,"of which the following is a specification.

This invention relates to an improvement in folding or collapsible pasteboard boxes designed more particularly for milliners use, although capable of extensive use in other directions.

It is the object of my invention to'provide a box suitable for such use which is of. such a shape as to take up small space and yet be attractive in appearance and be of great strength. I accomplish this by having a square base, with two sides running up to a point, so as to make preferably triangular ends, and the latter are so creased and folded as to give great rigidity when the box is in use.

With the foregoing object in view my invention consists in the peculiar construction and arrangement of parts hereinafter more particularly described and then definitely claimed. v i

In the drawings accompanying this application, which represent the preferable embodiment of my invention, Figure 1 is a perspective viewof the box in its folded condition with parts broken away. Fig. 2 is a similar view with one end unfolded. Fig. 3 is a perspective view of the box partly folded. Fig. 4 is a vertical section, and Fig. 5 is a View of the blank, and Fig. 6 is a view of parts of a modified. blank.

Referring now to the details of the drawin gs by letters, A representsthe blank, which is scored, as shown in Fig. 5, to form a bottom B and two sides D and E, which are preferably of substantially equal size, the bottom 13 being between the two sides D and E. The part of the blank on each side of the main parts B, D, and E is divided into six parts, which are markedF, G, G, H, I, and J, the first five of these forming one complete end and the last one, J, the latch which coacts with the slit d in the side D to lock the end of the box in its closed position. The opposite side E is also provided with a flap K, which I prefer to fold within the box, although it may be folded on the outside, if preferred. In addition to the partiK, I may also add a flap L, (see Fig. 6,) which when the flap K is folded inside maybe folded over the flap K and lockedto the side E bycausing its central part to enter the slot 6 in the side E. I also secure to each of the sides'Dand E flexible loops M and N, one of which may be slipped or looped through the other, whereby the box is not only locked, but-is provided with a handle by which it may be carried.

The foregoing is a brief description of the blank of which my box is formedand the method of folding the box is as follows: The blank is laid upon a table or suitable support, and the side D is bent upwardly from the bottom B, the end parts F being brought to vertical positions by bending the creases F inward and the creases H outward. The parts H can then be lapped over the parts F, with the wings Gipterposed between them. Theoperator now lifts the side E upward, when the outside ends I may be lapped over the opposing ends H, the wings G folding inside of said ends I. The operator may now fold the latches J around onto the side D and insert the tongues of the latches into the slots cl and securely lock the ends to the slanting sides. The loop M may now be drawn through the loop N and the box will be ready for the purchaser to carry away, the hat or other article purchased of course being placed on the bottom B of the box before the sides are folded, as just described, If the box is used with the additional locking-flap L, this flap is of course folded over the point of the box and slipped into the slit 6. (See Fig. 6.)

I desire to call special attention to the mannerin which my box is braced by the wings Grand the end parts F, H, and I. In the first place the part F is preferably of the exact size to extend from the corner of one side D to the corner of the opposite side E, and when the end part H and its flap G are folded over the part F its outer edge H fits exactlyin the crease formed by the parts G and the end part I as the latter fold over said part H. The said parts are thus interfolded,so as to form end braces, and when the latchJ is bent over and around the opposite corner and is secured to the side D it securely locks the parts in position, and the interfolded end braces are held where they are most effective. In fact,

ICO

the box is braced so well that it is remarkable how much pressure can be exerted on it without causing it to collapse, and boxes thus formed are so strong that they may be used in trunks with a full assurance to the traveler that the box is capable of resisting the great amount of pressure necessary in such rigid service.

What I claim as new is 1. A triangular box comprising in its construction a strip or sheet of material interfolded at its ends to form end braces, and an extension on one of said end braces adapted to extend over upon one of the sides of the box and be locked thereto, substantially as described.

2. A triangular box comprising in its construction a strip or sheet of material bent to form a bottom, sides and ends, the material being interfolded at the ends to form end braces, and an extension on one of said end braces adapted to extend over upon one of the sides of the box and a tongue for locking said extension to said side, substantially as described.

3. A triangular box comprising in its construction a strip or sheet of material bent to form a bottom, sides and ends, the sides projecting from the bottom and meeting at a point at the top, and the material at the end being interfolded to form end braces, one of said end braces having a tongue adapted to extend over upon the side of the triangular box and be interlocked thereto, substantially as described.

Signed by me at St. Louis, Missouri, this 2d day of October, 1901.
